Google Test  vs. Any other C++ testing framework

1. Pick the right tool for your particular task

2. Created per google needs, and has the following advantages:

• Google Test is designed to be portable: it doesn't require exceptions or RTTI; it works around various bugs in various compilers and environments; etc. As a result, it works on Linux, Mac OS X, Windows and several embedded operating systems.
• Nonfatal assertions (EXPECT_*) have proven to be great time savers, as they allow a test to report multiple failures in a single edit-compile-test cycle.
• It's easy to write assertions that generate informative messages: you just use the stream syntax to append any additional information, e.g.ASSERT_EQ(5, Foo(i)) << " where i = " << i;. It doesn't require a new set of macros or special functions.
• Google Test automatically detects your tests and doesn't require you to enumerate them in order to run them.
• Death tests are pretty handy for ensuring that your asserts in production code are triggered by the right conditions.
• SCOPED_TRACE helps you understand the context of an assertion failure when it comes from inside a sub-routine or loop.
• You can decide which tests to run using name patterns. This saves time when you want to quickly reproduce a test failure.
• Google Test can generate XML test result reports that can be parsed by popular continuous build system like Hudson.
• Simple things are easy in Google Test, while hard things are possible: in addition to advanced features like global test environments and tests parameterized by values or types, Google Test supports various ways for the user to extend the framework -- if Google Test doesn't do something out of the box, chances are that a user can implement the feature using Google Test's public API, without changing Google Test itself. In particular, you can:
  • expand your testing vocabulary by defining custom predicates,
  • teach Google Test how to print your types,
  • define your own testing macros or utilities and verify them using Google Test's Service Provider Interface, and
  • reflect on the test cases or change the test output format by intercepting the test events.
